uploading image files

Dear There,
I have a problem I uploading image files with an extension PICT. This message appears: “with error number -108”. Could you please advise me on this problem?
Thanks in advance,

The PICT file format is a very old Mac file format that is no longer supported by Apple. It was the standard Mac OS picture file format up until Mac OS 9, but that stopped being the case with Mac OS 10.0 back in 1999.

I suggest that you convert the files to another format like JPG or PNG.
